Enable u-boot.elf recreation from u-boot.bin to prepare for removing manul relocation. Enable option for big endian configuration but it is not used too much that's why it is completely untested. By supporting this system there is a need to define LITTLE/BIG endian Kconfig options to pass -EL/-EB flags.
Full command line for u-boot.elf recreation looks like this: microblazeel-xilinx-linux-gnu-objcopy -I binary -B microblaze \ -O elf32-microblazeel u-boot.bin u-boot-elf.o
